The basic direction of mathematical education for the 21st century is focused on helping student to understand mathematics and developing their problem solving abilities, mathematical disposition and mathematical thinking. Elementary mathematics teachers should help students make sense of mathematics, confident of their ability, and make learning environment comfortable for students to participate in. Through making activities 1 to 100 with digits 1,9,9,6, students improved the interest and preference of students about mathematics. This game is useful to foster students' mathematical thinking(concepts of exponential number expression, roots concept(${\sqrt}$), gauss function([])) and mathematical disposition. If students are helped to be interested in mathematics through mathematical games, they regard mathematics as interesting and challengeable subject to let themselves think many ways.

In energy dispersive X-ray fluorescence analysis, the removal of the continuum on which the X-ray spectrum is superimposed is one of the most important processes, since it has a strong influence on the analysis result. The existing methods which have been used for it usually require tight constraints or prior information on the continuum. In this paper, an efficient background correction method is proposed for Energy Dispersive X-ray fluorescence (EDXRF) spectra. The proposed method has two steps of background modeling and background correction. It is based on the basic concept which differentiates background areas from the peak areas in a spectrum and the SNIP algorithm, one of the popular methods for background removal, is used to enhance the performance. After detecting some points which belong to the background from a spectrum, its background is modeled by a curve fitting method based on them. And then the obtained background model is subtracted from the raw spectrum. The method has been shown to give better results than some of traditional methods, while working under relatively weak constraints or prior information.

Basic concept of this study is that architectural form as a material at present has meaning for the dweller's life on the past historical plane. Main method to recover history is ethnographic interview to dwellers. Secondary method is to analyze ancestors' writings, buildings in the background of the family photos, and past drawings and then to relate them with architectural form at present. Taxonomy is a starting point: general name of the building by outside researcher is quite different from it by inside dwellers. 'Haengrang-chae', servant quarter, has never been used for servants. Function of the haengrang went outside thatched houses at the front village. Firsthand observation or simple analyses as results of several precedent research are reexamined and criticized through this study. The mansion has moaning when we synthesize with the site location based on farming land and tenant farmer, and decline of the Kyongpo Lake. Territoriality of the mansion is reinterpreted to 'In-Out Structure' by Yin-Yang thinking, Dwellers extend buildings gradually to outside village, surrounding rear hills, the lake, DongHae Sea, and finally goes to imaginative Taoist heaven beyond real nature through the literary life. Confucius principle, known to govern upper class house at Yi Dynasty also affect general composition of the buildings: perpetuation of the family by ancestor worship, elder dominance and male dominance, fraternity love in the extended family, charity display by reception of guests, Taoist scholarly life harmonized with nature. However, the study of the particular life and usage of the dwellers reinforces or corrects general supposition of precedent researches. Unique shape of the house has been formed by convenience of the dwellers' life style, early modernized free thought over the rigid Confucius design principle, and female power in male dominant society.

The treatment of cleft lip and palate must be based on a complete knowledge of the anatomy, physiology and growth of the involved deformity, because of not only the appearance but also impaired functions such as phonation, mastication, respiration and lingual posture of the maxillomandibular complex. Delaire has long studied all these aspects, and has published many numbers of articles and constructed a philosophy concerning the significance and interrelationship of the various structures. The results obtained from its application seem to be particularly valid from a clinical point of view, although it has not all been scientifically supported by experimental data. For these reasons, Delaire's primary unilateral and bilateral cheilorhinoplasty procedures are particulary good, as is his secondary gingivoalveoloplsty procedure during the course of the surgical repair of the hard palate. In order to understand Delaire's philosophy, it is necessary to consider the normal and pathologic anatomy of the structures involved in the deformity, the role of some structures, such as nasal septum, musculature, and tongue, and some functions, such as dental occlusion or nasal respiration, which play important roles in maxillary and particularly premaxillary growth. Despite of important concept and meanings, Delaire's philosophy has not been introduced widely to our Korean cleft surgeons yet. So authors will summarize the basic concepts of Delaire's philosophy according to already published literatures and lectures based on our previous treatment outcomes.

This paper was written in order to study the correlation of Taeumin's symptomatic phamacology to Chinese Febrile medicine. Through the symptoms and Clinical cases, treatments of the epidemic febrile disease in ${\ulcorner}Dongyi$ Suse $Bowon\{lrcorner}$ , the symptomatic phamacology for Taeumin was compared with chinese febrile medicine. The following conclusions were reached as a result of comparing the epidemic febrile disease in Taeumin with Chinese febrile medicine. 1. The concept of the epidemic febrile disease in Chinese febrile medicine is wider than that of the epidemic febrile disease in ${\ulcorner}Dongyi$ Suse $Bowon\{lrcorner}$ 2. The cause of the epidemic febrile disease in Chinese febrile medicine is fevershiness almost, but the So-byung(An Natural-Ordinary Disease) of Taeumin in ${\ulcorner}Dongyi$ Suse $Bowon\{lrcorner}$ is the basic method to diagnose the symptom of the epidemic febrile disease. 3. The So-byung of Taeumin in ${\ulcorner}Dongyi$ Suse $Bowon\{lrcorner}$ is divided into feverish symptom and cold symptom according to the so-byung. 4. In ${\ulcorner}Dongyi$ Suse $Bowon\{lrcorner}$, The method of a curative means is based on differing dimensions of the Visera and bowels, but Chinese Febrile Medicine has a equal curative means irrelevant to a patient's character.

The pulse diagnosis is the basic method of oriental medicine diagnosis. But in sasang constitutional medicine, it is said that it's not a major diagnotic method. But we don't have any sasang constitutional study of the pulse diagnosis. So I made this study by research of changing concept of the pulse diagnosis in chinese medical history and Dongyi Suse Bowon (longevity and life preservation in oriental medicine). The conclusion as follows. 1. There were many kinds of the pulse diagnosis in the ancient times, it has developed to simple and effective diagnotic method. Simple and effective is the major point of medical development, the 24 pulse is abridged to Floating Pulse(浮), Deep Pulse(沈), Slow Pulse(遲), Rapid Pulse(數) 2. The latter term of Chosun, the practical study was developed. In the view of the practical study, the pulse diagnosis has a lot of cricical point. Jung Yak-Yong, in his writing Mak Lon(脈論), criticize the pulse diagnosis. 3. In the sasang constitutional medicine, the constitutional diagnosis is very important. The methods of the constitutional diagnosis are three, the way of mind and greed, knowledge and deed, external figure and physical traits. But the pulse diagnosis is one of the way of external figure and physical traits, so we can't diagnose the exact constitution by the pulse diagnosis. 4. Dong-mu conclude that the pulse diagnosis is just the diagnostic way of symptom. But in the clinical situation, the ordinary symptoms are more important than the pulse diagnosis, because it is useful to know the condition of the ingestive food metabolism and the Qi-yack metabolism

This paper reviews the most central analytical and methodological issues that arise in developing national STI strategies. First, an outline of the relationship between national innovation systems and the strategic dimension is presented. The paper shows that science, technology and innovation strategy are often used in different forms and that there is no common understanding yet of the actual meaning and coverage of these strategies. The paper develops the terminology from a discussion of different approaches towards company innovation processes analyzing their evolution in different socioeconomic environments and the role and impact of science, technology and innovation policy on company innovation processes. Based on this conceptual understanding the paper defines national science, technology, innovation, and STI strategy and explains the basic terminology. From these definitions, the strategic dimension including the impact on the stakeholders is discussed. It is shown that a major success factor for STI strategy development is the involvement of stakeholders to vary and extend their use of their portfolio of instruments. Moreover it becomes evident that stakeholders follow their own interests which aren't necessarily in the interest of the national STI strategies. The analysis shows advantages and disadvantages as well as potentials and limitations of different approaches to develop STI strategies in their ability to describe the reality of innovation processes and to allow conclusions about the relationship between innovation policy and the innovation processes implemented by companies. It is shown that knowledge of these limitations is an important factor to consider in designing consistent and coherent national STI policy which aims at supporting innovation eventually. Finally the paper concludes that the STI policy mix concept needs a more systemic development approach which is integrated in the national STI strategy development and implementation.

In recent years, parents of students and government have been taking a growing interest in education for the gifted students and there are many research reports about the gifted education. Most of the reports, however, focuses on the conceptional feature of the gifted education program such as organization, operation, management, evaluation, etc,. In other words, there are very few researches on instructional materials for gifted students even though the materials is a critical factor for successful education programs. So, this paper introduces a lecture notes used in a personal education for gifted students to contribute in developing education contents in computer science area. The instructional materials titled as "The Necessity and Application of Matrix in Computer Science" is based on linear equation to usher the students into creative problem recognition and groping for solutions. Also, the instructional materials is useful for students to understand the tight mathematics-computer science relationship and the basic concept of liner algebra.

Since the start of gifted education in 2002, educational support system has now been established, and sufficient growth in quantitative aspects has been achieved in Korea. On the other hand, they report that there are insufficient points in terms of education quality. In other words, most of the gifted education simply expands knowledge by prior-learning. In order to improve the quality of gifted education, they should enhance critical-thinking and creativity able to apply interdisciplinary principles or phenomena for solving problems. In this study, we designed and developed a convergent teaching-learning materials based on the concept of integrated education, which explore the process that basic logic operations such as AND, OR, XOR do the role of computer cells. A survey result showed that student satisfaction(usefulness, understanding, interest) of the materials is significantly higher than that of other traditional learning topics, and the design intent was met.

The primary purpose of this paper is to critically examine the theoretical and methodological issues in the study of generations. The issues include: 1) the concept of generation: 2) the basis of generational formation: 3) internal differentiation of generations: 4) the boundary problems of generations: 4) the boundary problems of generations: and 5) generational differences and generational conflict. From the investigation of these issues, two conclusions are drawn. Firstly, Mannheim's basic concepts and theoretical frameworks are very useful to understand and explain the social movements and sociocultural changes. Secondly, however, further elaboration and modification of the several concepts and frameworks are needed to deal with the problems of generations in general which are not directly connected to social movements. Several points are suggested to elaborate Mannheim's frameworks, which include the reconceptualization of generation, and introducing the concepts of “generation sects” and “manifest-latent generational conflicts”.
